Wegovy pill (oral semaglutide 25 mg) or Phentermine (generic): which publishes a price?
Only one of these two publishes a verified all-in price, which settles the comparison before any other axis is reached: Wegovy pill (oral semaglutide 25 mg) at $149–$199, and no figure at all for the other. Wegovy pill (oral semaglutide 25 mg) is the better choice of the two (halfrx score 6.4 against 3.1). Every axis below is computed from stored fields rather than written by hand, so the comparison moves when a price does. Neither carries an FTC action, a state action, a BBB F grade or an FDA warning letter. One is generic and the other brand, which is the difference between an FDA-approved product and a copy made under the compounding exemption. The published formula scores them 3.1 and 6.4 out of 10, arithmetic over the same stored fields rather than an editor's preference.

Read the price gap carefully: these two are not the same purchase
- These are different molecules — Phentermine (generic) on phentermine, Wegovy pill (oral semaglutide 25 mg) on semaglutide — so this is a comparison of two treatments, not of two prices for one.
Phentermine (generic)
Pros
- +The cheapest drug in the category by two orders of magnitude: $0.068 a tablet at pharmacy acquisition cost against $263 for one Zepbound pen.[2]
- +Covered by more Medicaid programmes than any GLP-1 — seven states cover an older weight-loss agent while covering no GLP-1 at all.[3]
- +One tablet each morning, no injection, no titration schedule beyond a possible half dose.[1]
Cons
- −Approved for a few weeks only. Every monthly subscription selling it as ongoing therapy is using it off the label's own duration.[1]
- −Schedule IV controlled substance, chemically related to the amphetamines, with the dependence warnings that follow from that.[1]
- −Stopping after prolonged high dosing brings extreme fatigue and depression, per the label — which is a hard exit from a subscription that sold it as maintenance.[1]
- −No cardiovascular outcome data of the kind the GLP-1s now carry, and contraindicated where blood pressure is uncontrolled.[1]
Wegovy pill (oral semaglutide 25 mg)
Pros
- +16.6% mean weight loss in OASIS 4 — the strongest result of any oral weight-loss drug approved to date.[5]
- +No injections, no needle disposal, no refrigeration.[4]
- +Self-pay from roughly $149/mo direct from Novo Nordisk, against $1,349 list for the injection.[3]
- +Same molecule as Wegovy injection, which has years of post-marketing safety data behind it.[4]
Cons
- −The $149 price on the 4 mg dose expires on 31 August 2026 and becomes $199. If you are pricing this in late August, you are looking at a number with days left on it.[2]
- −The published prices cover the titration strengths only. Novo does not publish what the 25 mg maintenance dose costs, which is the price you would actually live with.[2]
- −Oral semaglutide has strict dosing conditions — taken on an empty stomach with a small sip of water and nothing else for 30 minutes. Adherence in the real world is worse than in trials, and the 16.6% figure is the adhered-to result.[5]
- −Telehealth programmes mark it up hard: Ro at $373, Hims and LifeMD at $448 for a drug Novo sells near $149.[6]
- −Still trails tirzepatide injection on average weight loss.[3]
- −Launched January 2026 — supply and pharmacy stocking are still uneven.[4]
